This is according to data collected by Shopatron’s patented Order Exchange, which powers the e-commerce orders for more than 1,000 branded manufacturers and leading multichannel retailers.

Fueled by the rise in smartphone usage, the biggest online shopping day in history also included a record number of mobile transactions, accounting for 20 percent of Cyber Monday order volume — a 54 percent increase over last year.

Additionally, promotional strategies remained an important piece of Cyber Monday sales, with 46 percent of Shopatron Manufacturer orders being tied to a promotion. More specifically, 37 percent of Shopatron Manufacturer orders were tied to a free shipping promotion, indicating that eliminating shipping costs is an effective way to drive online sales.

Shopatron’s e-commerce order management platform also broke two records of its own this Cyber Monday: capturing the most GMV and number of orders in a single day throughout the company’s 12-year history, the company said.

“Today’s shoppers are more digitally sophisticated than ever before,” said founder and CEO Ed Stevens. “Shopatron’s efforts to streamline the shopping experience across channels — on mobile phones, in-store and online — are successfully driving e-commerce sales and strengthening customer loyalty for its clients.”
